For the first time, we saw our world, not as a solid, immovable, kind of indestructible place, but as a very small, fragile-looking world just hanging against the blackness of space.

In science, there are no universal truths, just views of the world that have yet to be shown to be false.

Science is different to all other systems of thought because you dont need faith in it, you can check that it works.

If people don’t have an understanding of what science is and what scientists do, then they can tend to think that global warming, for example, is just a matter of opinion.

Every carbon atom in every living thing on the planet was produced in the heart of a dying star.

When we look out into space, we are looking into our own origins, because we are truly children of the stars.

What scientists are attached to is journeys into the unknown and discovering things that are completely unexpected and baffling and surprising.
